ABSTRACT
The sugarcane hairy borer, Hyponeuma taltula (Schaus, 1904), attacks the base of sugarcane and causes the death of the apical bud, a symptom known as "dead heart." In recent years, there has been significant infestation in Brazilian sugarcane crops. With the purpose of finding methods for controlling and/or monitoring the pest for the sustainable cultivation of sugarcane, we characterized the mating behavior of H. taltula and confirmed the release of a sex pheromone by this insect. Sexual activity was observed between the second and ninth hour of scotophase, during which female calling caused the onset of male courtship behaviors and increased their frequency. An ethogram was built showing that males perform seven observable steps: (1) wing flapping, (2) walking with wing flapping, (3) flying, (4) flying towards the female, (5) landing near the female and walking around her, (6) attempting copulation, and (7) copulation (mating). Female sex gland extracts also triggered attraction and male courtship behaviors. These results thus confirm that the female abdominal gland produces a sex pheromone and that the presence of this pheromone in the air is needed to initiate the male courtship sequence. The sexual behavior of H. taltula is compatible with control and/or monitoring methods using female sex pheromones.

INTRODUCTION: The lung transplantation (LTx) program began in Ceará in 2011 and the first LTx was performed on June 11, 2011. The aim of this study was to present the initial results of the 6-year experience of our program. METHODS: We retrospectively reviewed our experience on LTx from June 2011 to August 2017. Data on recipients and transoperative and postoperative outcomes were recorded in a database. RESULTS: Twenty-two (56.4%) were single LTx, 15 (38.5%) were double, and 2 (5.1%) bilateral lobar. The mean age was 47.5 ± 15 years, and 26 (66.7%) were men. Twenty-eight (71.8%) had pulmonary fibrosis; 5 (12.8%) had pulmonary emphysema, 3 (7.7%) had bronchiectasis; 2 (5.1%) had pulmonary hypertension, and 1 (2.6%) had lymphangioleiomyomatosis. Complications occurred in 82% (32/39) and in-hospital mortality was 30.8% (single LTx = 27.8% and double LTx = 33.3%). The main complications were infection in 17 (43.5%) cases and primary graft dysfunction in 7 (17.9%). There was a significant improvement in pulmonary function in the first year of follow-up (forced expiratory volume pre-LTx = 37% ± 16% and 12 months post-LTx = 72% ± 22%, P = .001); and overall survival at 36 months was 59.0%, with no difference between single- and double-lung transplants. CONCLUSIONS: Idiopathic pulmonary fibrosis was the most common underlying disease and single LTx was the most commonly performed operation. There was a high incidence of postoperative complications and in-hospital mortality, but the 36-month follow-up showed a marked improvement in lung function and a global survival similar to the literature.

Odontomas represent the most prevalent odontogenic tumors in the jaw. The treatment of choice is surgical removal, usually performed by conventional techniques involving ostectomies to expose the tumor. In this paper, the authors describe, through the report of a case of complex odontoma located in the mandibular angle, a more conservative surgical technique called corticotomy, in which the bone removed for access to the tumor (buccal cortical) is repositioned and fixed by titanium plates of 1.5 mm.

A thirty-three year old woman, known to have Kearns-Sayre syndrome for eight years, had an ECG pattern of right bundle branch block and left anterior fascicular block that evolved to complete atrioventricular block, leading her to a syncopal episode. A temporary pacemaker and a permanent one were installed. The patient has been asymptomatic so far.
